So basically I had set a breakpoint on a WINAPI function call. When I tried to run the program and step over the breakpoint, the program exits with the popup window: `unknown exception code 6F4 (exc.code 6f4, tid 704)`. The function does not return any value as the program exits before that happens, so I can't tell if the function has returned a successful error code or not. What is this exception code, and why did this happen?
